The Rotor 39T (53) BCD110x4 Inner Round Chainring is designed for performance road setups using a traditional 53/39T combination. Its gearing is suited to fast group rides, racing and sustained efforts on rolling terrain.

Matched 53/39T Combination: This 39T inner chainring is developed to pair with a compatible 53T outer chainring. Using the intended combination helps maintain controlled front shifting and consistent drivetrain performance.

Consistent Round Pedalling: The conventional round profile provides predictable resistance throughout every crank rotation. It is ideal for riders who prefer a familiar pedalling feel and direct power delivery under changing loads.

Four-Arm Road Compatibility: The 110 mm four-bolt mounting pattern works with compatible Rotor cranksets and selected Shimano four-arm road crank systems. The chainring is intended for suitable 10 and 11-speed road drivetrain configurations. 

The Rotor 39T (53) BCD110x4 Inner Round Chainring delivers race-focused gearing, dependable shifting and familiar round-ring performance.
